I was just wondering. Energon Superion Maximus combiners were designated A1 thru A5, Constructicon Maximus combiners were C1 thru C5 and Bruticus Maximus combiners were D1 thru D5. Why was B1 thru B5 skipped? Could there have been another combiner planned in the very early stages that would have been designated B1 thru B5? Maybe another Autobot to even out the group with 2 Autobots versus 2 Decepticons? Maybe a Defensor Maximus combiner?
